Here is a CSV with the result from a scan I did.The MD5 and CSV was created by a quick tool I made myself, the actual stats was gathered with Sox using the following params. (thanks again bandpass for your sox knowhow).

sox.exe file.wav -n stats upsample 4 sinc -a 40 -t 8k -24k stats

The two stats (peak and rms of the first stats, and the peak from second stats with a +12.04 adjustment to counter the attenuation during the upsampling in sox)

Here follows just one example of the numbers you can do on the attached csv data. Have fun. (PS! the MD5 id is local to the scan/csv file only)CSV format is: id,peak,rms,isppeak and rms and isp are all relative to 0 dBFS (0dBFS = +1.0 or -1.0 floating point).
